Add to that that HDD support includes "SATA" HDD as it is very hard to find a PATA (IDE the OLD wide data connection) SSD.
Depending on age it could use a IDE HDD and a IDE DVD drive. Laptops first migrated to SATA HDD and Pata DVD drives -> both being SATA.
I guEss im just worried about a new ssd not working despite the laptop using 2.5" and sata connections but the motherboard itself doesnt recognize ssds. For example if i needed to update motherboard drivers just for it to recognize the latest ssds.
